Emerging Marine Biotoxins in European Waters: Potential Risks and Analytical Challenges [PDF]
Marine Drugs, 2022 Harmful algal blooms pose a challenge regarding food safety due to their erratic nature and forming circumstances which are yet to be disclosed. The best strategy to protect human consumers is through legislation and monitoring strategies. Global warming

Evaluating Bias in Self-Reported Symptoms During a Cyanobacterial Algal Bloom [PDF]
ToxinsAlgal blooms produced by cyanobacteria liberate microcystins and other toxins that create a public health hazard. During the 2018 bloom of Microcystis aeruginosa in Florida, USA, residential and recreational exposures were associated with an increased ...

[Ciguatoxins and brevetoxins: dissection of the neurobiological actions].
Journal de la Societe de biologie, 1999 This review focuses on the neurobiological actions of ciguatoxins and brevetoxins which are phycotoxins produced respectively by the dinoflagellates Gambierdiscus toxicus and Ptychodiscus brevis. These actions are illustrated in particular by the effects of the toxins on myelinated nerve fibres and on skeletal neuromuscular junctions of vertebrates ...

Total Synthesis of Brevetoxin A [PDF]
Organic Letters, 2008 A total synthesis of brevetoxin A is reported. Two tetracyclic coupling partners, prepared from previously reported advanced fragments, were effectively united via a Horner—Wittig olefination. The resulting octacycle was progressed to substrates that were explored for reductive etherification, the success of which led to a penultimate tetraol ...

Detection of Brevetoxin in Human Plasma by ELISA. [PDF]
J Anal Toxicol, 2022 Abstract Florida red tides have become more common and persistent in and around the Gulf of Mexico. When in bloom, red tides can produce brevetoxins in high concentrations, leading to human exposures primarily through contaminated food and ocean spray.

Total Synthesis of Brevetoxin-B [PDF]
Journal of the American Chemical Society, 2003 Brevetoxin-B (BTX-B), produced by the red tide organism, Gymnodium breve Davis, is the first member of marine polycyclic ethers to be structurally elucidated and one of the most potent neurotoxins. The structural feature is a trans-fused polycyclic ether ring system with 23 stereocenters.
